Minimum capital requirements

Minimum capital requirements:

Banks and bank holding companies are subject to regulatory capital requirements administered by federal banking agencies. Capital adequacy guidelines and, additionally for banks, prompt corrective action regulations involve quantitative measures of assets, liabilities, and certain off-balance sheet items calculated under regulatory accounting practices. Capital amounts and classifications are also subject to qualitative judgments by regulators. Failure to meet capital requirements can initiate regulatory action.

Under regulatory guidance for non-advanced approaches institutions, the Bank and Company are required to maintain minimum amounts and ratios of common equity Tier I capital to risk-weighted assets. Additionally, under Basel III rules, the decision was made to opt-out of including accumulated other comprehensive income in regulatory capital. As of June 30, 2019 and December 31, 2018, the Bank and Company met all capital adequacy requirements to which they are subject.

Beginning in 2016, an additional conservation buffer was added to the minimum requirements for capital adequacy

purposes, subject to a three year phase-in period. As of June 30, 2019 and December 31, 2018, the buffer was 2.50% and 1.88%, respectively. The capital conservative buffer was fully phased in on January 1, 2019.

Actual and required capital amounts and ratios are presented below at period-end.
